Description Foamed gel is a dispersion of gas encapsulated in a continuous cross-linked external phase that may be a plastic, a water-soluble polymer gel, or a colloidal silica gel, Foamed gel has recently been used to plug porous media for the purpose of physically controlling the movement of subsurface fluids, The performance of foamed gel barriers is directly related to the pore level configuration of the foamed gel, specifically, the number and location of gelled lenses that plug flow paths, The pore level configuration of foamed gel changes because of gas diffusion from small bubbles to large bubbles during the shut-in period for gelation that follows foam generation, The evolution of a foamed gel's texture in porous media has been studied using etched glass micromodels to determine what factors influence the final number and location of gelled lenses, Because the foam disproportionation was so rapid, gelation reactions that restrict gas diffusion must occur within approximately 20 min in order to maintain the initial distribution. Because the walls of the pore body prevent bubbles from exceeding the diameter of the pore body, any multiple pore spanning bubbles formed will coexist indefinitely, It was found that the number of pore spanning bubbles increases as the pore body aspect ratio (pore length/pore width) increases.
